sorry people, i have another thread that has all i was questioning about, the thread is Markbass tube 800 head blew. let me know it you have any answers for me, thanks
Job #1 would be to check that the speaker cable isn't/wasn't shorted. Sometimes they can short out if bent a particular way.
When you say "blew," what does that mean? Won't power up? Powers up but no sound? If it powers up but there's no sound, is there anything coming from the preamp output (or effects out)?
